Abstract. The purpose of the present paper is to examine the relation-
ships between target and concatenation costs and the quality (with focus
on naturalness) of generated speech. Several synthetic phrases were ex-
amined by listeners with the aim to find unnatural artefacts in them, and
the mutual relation between the artefacts and the behaviour of features
used in given unit selection algorithm was examined.
Key words: speech synthesis; unit selection; quality evaluation; unnat-
ural artefacts; target and concatenation cost
1 Introduction
The quality of synthetic speech, especially its naturalness, represents an issue
which still remains open. Although the unit selection approach, or the modern
HMM–based synthesis, are able to reach fairly high level of naturalness, there
are still unnatural artefacts of a different nature (depending also on the syn-
thesis method) occurring in synthesized speech when input text comes from the
unlimited domain.
The paper evaluates unnatural artefacts (also called glitches ) perceived in
speech generated by unit selection incorporated in our TTS ARTIC [1–3], and
attempts to reveal the relation between those artefacts and the behaviour of
features used for target and concatenation costs computing. There have been a
number of papers written, mostly focusing on the relation of human perception
to spectral subcost of concatenation cost only – [4–10] belong among those most
important. However,
